Subject: [PATCHv2 01/31] ARM: dts: r8a7790: Reference both DMA controllers in SCIFA nodes
Date: Tue, 15 Mar 2016 13:41:38 +0100	[thread overview]
Message-ID: <1458045728-4758-2-git-send-email-niklas.soderlund+renesas@ragnatech.se> (raw)
In-Reply-To: <1458045728-4758-1-git-send-email-niklas.soderlund+renesas@ragnatech.se>

R-Car Gen2 have two DMA controllers, which are equivalent. Add
references to both dmac0 and dmac1 so the driver can fallback to the
later if the first one is unavailable.
